DOM nodes garbage collected?

Created by: reiniervandijk

Each time user visualizes something in Tasty in X3D format (true for other formats as well), Gendl server responds with a new wrl file to embed. What happens to the previous embedded DOM elements? Are they garbage collected in the browser, or do they stay alive? I know a DOM by default preserves all DOM nodes, even if they have been removed from the DOM tree itself. Only a page refresh would drive the browser to gc. See:
